Red and Yellow.. symbolic of Russia, China?
Those Drive Caddies look like the ones from a RAID Enclosure. Those two Drives could be Spares, from an Array, where the vDisk only spans eight of the ten Drives in the Picture. Six drives are on the Counter, the empty Caddies are on the right. The four Drives remaining in the Stack on the left are still in the Caddy, or so it appears. Two Drives are marked wiped, so spares for the Array. Like a RAID 1/5 Array. This setup is popular with Government and MIL Raid Arrays for redundancy. Pic related. Don't ask.
